Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed May 14, 1906. Serial No. 316,656.

T 0 all whom it may concern:

Be it known that I, HENRY FRANCIS KEIL, a citizen of the United States of America, and a resident of Bronxville, in the county of Westchester and State of New York, have in- Vented a certain new and useful Look, of which the same is a specification, the same being a full, clear, and exact description of the invention, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to. a pliances for securing in position doors and ike movable articles, and in particular to looks and latches adapted to be inserted in a notch or recess in the stile of a door and having a combined escutcheons and face plate having means to reinforce the said escutcheons, and which embody certain novel features of construction and combination and arrangement of parts, of sim le construction and efficient in operation, a l of which will be hereinafter described and fully illustrated in the drawings.-

To attain the desired end, this, my invention consists in the construction, arrange ment and operation of parts herein set forth.

In order to enable the invention to be fully understood I will proceed to explain the same by reference to the drawings, illustrative of one embodiment of the invention, which accompany and form a part of this specification, and in which Figure 1 is a section through the knobs and Fig. 2 a plan view of a lock constructed according to this invention; and Fig. 3 is a view in detail of the face plate adjusting mechanism.

Like letters of reference indicate like parts in all the views.

Referring particularly by letter to the drawings A, A denote my combined escutcheons and face plate which rests against the sides of a door and extends around its front edge and overlaps the notch C, and which is preferably made of sheet metal. The combined escutcheon plates A and face plates A is of a unitary construction, so far as its functions in supporting within the same the lock-case D (which contains a suitable lock or latch mechanism) and in serving as a covering for the notch or recess is concerned, may be considered as an entirety no matter whether it is integral and is made of a single piece of metal, as shown in Fig. 1, or whether it is composed of a plurality of plates rigidly fastened together, as illustrated in Fig. 2.

B designates the knobs and B the shanks of the same which may, pass through the preferably loose knob roses B carried by the escutcheon plates and lie respectively adj acent to and rest against the sides of the lock-case D which is a complete article of itself consisting of the body d and cap d and is supported within the combined escutcheons and face plate by means of screws inserted into the front of the lock-case through the face plate A The lock-case D is inserted into a recess, notch or mortise C formed in the edge of the door preferably by simply sawing a piece out to the depth of the lock, and the top and bottom edges a, a (or, as it were, notch overlapping edges a of the escutcheon plates, extensions thereof projecting toward the lock face, and edges a of the face plate) being of greater dimensions or size than the opening or recess in the door, overlap the same, and thereby entirely cover or frame in the mortise and conceal any possible poor cutting out of the door, in the event of the same being carelessly or hastily done. The top and bottom edges a, a also serve to afford resistance flanges or borders or stops, in order to prevent any danger of the look from being pulled out of its position to any degree, the lock case being also provided with means to engage the knob spindles.

The combined escutcheons and face plate not only forms a protection to the wood of the door, but the said structure is very readily applied and quickly attached to the door by simply slip ing the combined escutcheons and face p ate over the edge of the door and then screwing the escutcheons in place.

This invention is applicable to all kinds of doors to which mortise or rim locks can be attached, and is manifestly applicable to both locks and latches, or a combination of the two.

I provide simple means for adapting my combined escutcheons and lock-face to be used for doors of different thicknesses, which preferably consists in making the same so as to be expansible as regards the width of the lock-face as, in the present embodiment, by forming the same with a plaited or folded lock-face, the folds or plaits a of the same ordinarily lying between the lock-case and the extensions of the escutcheons. Two strips a, are cut from the to and bottom edges of each of the folds or p aits (1 which strips are bent toward each other so as to lie the lock rose on each side of the same.

behind the lock face and to present a practically unbroken edge of the lock face adjacent to, and above and below, the said folds.

In case the combined escutcheons and lock-face is ap lied to a thin door the seam between the fol ds a will be closed, but in the event of the structure being used in connection with and attached to a thick door, as in Figs. 2 and 3, the folds will be opened somewhat when the combined escutcheons and lock-face is forced on the edge of the door in order that the expanded lock-face may register with and conform to the edge of the door. The shanks of the screws E may work in threaded holes in the sides of the lockcase and may be operated by a tool inserted in the orifices a formed in the extensions of the escutcheons, by which means the folds or plaits a of the lock-face may be spread apart and the adjustability or expansion of the lock-face regulated.

In some ,cases I construct the combined escutcheons and'lock-face of such a width, when formed up, as will conform to a standard thickness of a door, and to that end the escutcheons are then permanently held apart a certain distance by the lock-face, which is fixed in width and not laterally expansible.

I sometimes construct the knob roses B so as to be hollow or shell-like in form, as in Fig. 1, the bores of the same being larger in size than the diameter of the knob spindles, and the said knob roses being in this case loosely carried by the escutcheon plates. The orifices A formed in the escutcheon plates are also larger than the knob roses encircled by the same, and the knob shanks are constructed and arranged to respectively lie adjacent to and to bear directly against In other cases I construct the knob roses B so as to be fixed on the escutcheons. That is to say they may be integral, 4;. e. the escutcheons and knob roses, or else the knob roses may consist of separate pieces rigidly attached to the escutcheons by any suitable means. The orifices A formed in the escutcheon plates are larger in diameter than eons, as the plates F, which lie between the preferably flexible escutcheons and the sides of the door, by which meansthe plates F 'being rigid and preferably made of cast metal orheavy hard wrought material resistance means is afforded whereby upon any pulling or undue strain on a knob, the preferably non-integral hubs of which rest against the escutcheons, any displacement of the lock will be prevented, the reinforcing plates F obviating any danger of the bending or distortion of any of the parts of the escutcheons.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

In this application, I claim only the reinforcing means for the escutcheons, as the combined escutcheons and face plate, per 86, together with the other features of the invention disclosed, but not claimed herein, are claimed broadly in my application for patent filed April 10, 1906, Serial No. 310,929.

What I claim as my invention is In a lock,- a combined escutcheons and face plate to rest against the sides of a door and extending around its front edge and of greater dimensions than and overlapping a notch cut in the stile of the door, a lock-case inclosed in and supported by the said structure, means lying adjacent to an escutcheon to reinforce the same, 'and means whereby the face plate may be expanded in width.

In testimony of the foregoing specification I do hereby sign the same in the city of New York, county and State of New York this twenty fourth day of April 1906.
